Comedian John Oliver continued his attack on televangelism and the Internal Revenue Service during Sunday's "Last Week Tonight," where Oliver started his own "church" and asked viewers for donations.

Last week, Oliver criticized some televangelists for asking viewers for "seed" money in change for blessings, which he charged was only used to enrich the ministers. Then he slammed the IRS for conducting only three audits of churches from 2009 to 2014.

"In order to prove how ridiculously easy it is to establish a tax-free 'church' that pads its coffers with donations for 'blessings,' Oliver established his own church — Our Lady of Perpetual Exemption — and asked his viewers to send cash donations to a P.O. Box that he'd then donate to charity," wrote the Daily Beast's Marlow Stern.

"They keep trying to send more money, more money, more money so they can get healed," Anthony told CBS News about the people giving to the ministries. "A few years ago, the IRS named Scientology a church. Since that happened, anybody can call themselves a church."

Erik Stanley, senior counsel for the Alliance Defending Freedom, told CBS News, though, that churches already do a good job at policing themselves and that the churches' tax exemptions are enshrined in the U.S. Constitution.

"You are always going to find abuses and excesses in the nonprofit community, and even in the church world," Stanley said to CBS News. "There is no surer way to destroy that free exercise of religion than to begin to tax it."
